Among HIV-infected individuals, non-injection drug use (NIDU) is associated with poor HIV medication adherence, greater HIV/AIDS risk behaviors, and increasing non-AIDS mortality. Thus reducing NIDU among HIV infected individuals is critical to their survival and to limiting the spread of HIV. We propose to study the efficacy of a technologically enhanced brief intervention (HealthCall) to reduce NIDU in HIV primary care patients that demands little from busy medical staff and is well accepted by patients. In a 3-arm randomized clinical trial will test the efficacy of (a) Motivational Interviewing (MI)+HealthCall; (b) MI-only; and (c) a control condition (advice + DVD HIV health education) in reducing NIDU.
